Japan Post Bank Co has a rich history that dates back to 1871, when it was established as a postal savings system to collect deposits from the public.
The bank's early success was largely due to its unique business model, which allowed it to offer low-interest loans to the government while still providing competitive interest rates to depositors.
In 2006, Japan Post Bank Co was privatized and became a separate entity from Japan Post, a state-owned postal and logistics service provider.
Today, Japan Post Bank Co operates a vast network of over 24,000 branches and ATMs across Japan, making it one of the country's largest financial institutions.

Founding Through WWII
The Japanese postal banking system has a rich history that dates back to 1875 when Maejima Hisoka, known as "the father of the Japanese postal system", started the postal savings system.
Maejima was inspired by the UK's postal savings services and quickly gained popularity, with 10,000 customers within the first three years.

The postal savings system was relaunched in 1949 under the newly formed Ministry of Posts and Telecommunications after World War II.
By 1960, postal savings had grown to ¥1 trillion, and by 1985, it had reached ¥100 trillion.
The postal savings system continued to thrive, and in 2001, it came under the jurisdiction of the Postal Services Agency, which later reorganized into Japan Post in 2003.
This marked an important step towards the eventual privatization of Japan Post Bank, which began in 2007.
